Boston Marathon blasts kill two and injure many more

Update CBS News in the US are reporting that a Saudi national is being questioned by the FBI. He denies any involvement in the attack

In a press conference just now, President Obama has made clear that the Federal Authorities do not know who is responsible for the attack on the Boston Marathon. But it was noticeable that he did not call it a ‘terrorist’ attack.

Meanwhile in Boston, the authorities there have denied reports that anyone is in custody—there had been chatter in the US media that a Saudi male was under arrest in Boston.

So far, no individual or organisation has claimed responsibility for this attack.
